Why Did the FDA Ban this Basic Amino Acid?

1 comment by Oskar Thorvaldsson

The story about how and why the FDA banned the amino acid, tyrptophan, highlights the how far back the problems and contradictions in the agency go. In 1989, as many as 10,000 people got sick, and around 100 people died, from consumption of tryptophan that was made from genetically modified bacteria. The epidemiologist who tracked the disease raised concerns about GMO and was quickly chastised by the FDA for doing so. It took years to confirm his suspicion that the GMOs were the cause. The FDA argued that since there were a few dozen cases of the disease, prior to the most recent GMO strain developed in 1989, that there was some other cause than the genetic modification.

Later, the epidemiologist, and subsequent researchers like William Crist, were proven correct about the GMO being the main cause, and that the FDA had lied not only about two dozen cases (there were hundreds) but also about there not being any GMO strains of bacteria used prior to the major outbreak in 1989. However, it was discovered that the Japanese company that made the tryptophan had been using other strains of GMOs since 1985, which suggested that these strains could be the source after all. Officials at the FDA denied this, however, and declared that tryptophan was part of a health supplement “fraud” and therefore should be banned across the country, regardless of its source.

The FDA has continually ignored studies showing that GMO-produced strains can create unknown toxins and unpredictable effects including what happened in the late 80s and early 90s. Today, things are no better, and even though the ban on tryptophan was lifted, there is no requirement to even test GMO-derived food crops or supplements. How can the FDA then say no one has ever been hurt by GMOs when they have? And why does the FDA continue to prevent GMO labeling, even though 90% of Americans want it? Rutgers Law Journal, regarding the tryptophan debacle said that the FDA, “has far more to do with eliminating competition in the pharmaceutical industry than preserving the public health.” (1).  

High Food Sources of Tryptophan

Most people do not need supplementation of of tyrptophan, as its found in many food sources. 

  • Cheese (1 cup = 177%
  • Bananas (1 cup - 5%)
  • Avocados (1 cup = 14%)
  • Fish (1 cup = 90%)
  • Potatoes (1 cup = 7%)
  • Pistachios (1 cup =  76%)
  • Organic Oats (1 Cup = 31%)

Seeds of Deception: Exposing Industry and Government Lies about the Safety of the Genetically Engineered Foods You’re Eating by Jeffrey Smith, former executive with a laboratory testing for GM presence in foods.

“The stories Smith presents read like a mystery novel. Scientists are offered bribes or threatened; evidence is stolen; data withheld or distorted. Government scientists who complain are stripped of responsibilities or fired. The FDA even withheld information from congress after a GM food supplement killed nearly a hundred people and permanently disabled thousands. While Smith was employed by the laboratory he was not allowed to speak on the health dangers or the cover-up. No longer bound by this agreement, Smith now reveals what he knows in this groundbreaking exposé.”

GMO Myths & Truths: A Citizen's Guide to the Evidence on the Safety and Efficacy of Genetically Modified Crops and Foods by Claire Robinson, John Fagan, PhD, and Michael Antoniou PhD

"Some would have us believe that the case against genetically modified (GM) crops and foods is based on emotion, not science, and that to oppose GM crop and food technology is to be anti-science. The same people claim that GM crops offer higher yields and better nutrition, that they are safe for health and the environment, that they reduce agrochemical use, and that they are needed to feed the world's growing population. This book, co-authored by two genetic engineers and a writer/researcher, exposes these claims as false, using scientific and other documented evidence."

Altered Genes, Twisted Truth: How the Venture to Genetically Engineer Our Food Has Subverted Science, Corrupted Government, and Systematically Deceived the Public by Steven Druker

"This book uncovers the biggest scientific fraud of our age. It tells the fascinating and frequently astounding story of how the massive enterprise to restructure the genetic core of the world's food supply came into being, how it advanced by consistently violating the protocols of science, and how for more than three decades, hundreds of eminent biologists and esteemed institutions have systematically contorted the truth in order to conceal the unique risks of its products–and get them onto our dinner plates.

Altered Genes, Twisted Truth provides a graphic account of how this elaborate fraud was crafted and how it not only deceived the general public, but Bill Clinton, Bill Gates, Barack Obama and a host of other astute and influential individuals as well. The book also exposes how the U.S. Food and Drug Administration (FDA) was induced to become a key accomplice--and how it has broken the law and repeatedly lied in order to usher genetically engineered foods onto the market without the safety testing that's required by federal statute. As a result, for fifteen years America's families have been regularly ingesting a group of novel products that the FDA's own scientific staff had previously determined to be unduly hazardous to human health."
